Attemping to compile and run the above code

1.Will cause a compilation error - a Layout cannot be set after a component has been added with a preset Layout Manager. 2.Will cause a Runtime Exception - a Layout cannot be set after a component has been added with a preset Layout Manager. 3.Will compile cleanly and throw no runtime Exception. Only the button with label "Center" is visible and occupies the whole screen. 4.Will compile cleanly an throw no runtime Exception. All the buttons are arranged in a single line. Any other component added in future will follow the rules of the BorderLayout Manager. 5.Will compile and run cleanly, but no component is visible. 6.Will compile cleanly and throw no runtime Exception. The buttons are arranged as listed below Button Label Position Center Center North North South South East East West West ans is 5, why the component is not displayed? -Arun

BorderLayout and CardLayout are the uniques AWT LayoutManagers that don't know how to rearrange components previously added.
